3.5ml of sodium hydroxide solution with c(NaOH)=0.052 mol/l is used for titration of gastric juice in the presence of phenolphtalein . Calculate total acidity of gastric juice and evaluate the result obtained.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
